The essential foods that help you fill up, slim down and stay healthy have one common denominator: fiber.
Companies are touting the fiber content of their products right on the label, which has paid off in sales. And if you choose the right foods, it will pay off for you, too.
You should get 25 to 30 grams of fiber a day, but most Americans barely get half that, according to "GMA" medical contributor Dr. Marie Savard.
Fiber not only helps your waist line, it's great for colon health and lowering "bad" cholesterol, and can alleviate constipation and diverticulitis, a digestive disease. Because it slows sugar absorption, Savard said, fiber also minimizes the insulin spike that can cause metabolic syndrome (a combination of conditions that can lead to heart disease and diabetes).
If that isn't enough, Savard said, she "first got addicted to fiber when I was pregnant with my firstborn" because it helps with hemorrhoids. Pregnant women should be sure to make fiber part of their diet, she said.
Introduce more fiber into your diet gradually and vary your fiber sources so you don't get bored with the same foods, Savard said. She recommends drinking a lot of water, because fiber can cause gas and bloating.
5 Essential Foods With Fiber
Whole Grains: Brown Rice, Wheat Bran Cereals
You can get fiber from bran cereals such as Fiber One, which has a whopping 14 grams of fiber in a half cup serving, and All Bran, which has 10.4 grams in a half cup serving, which has 90 calories.
You can double your fiber intake simply by switching from white rice to brown rice, Savard said.
Nuts and Seeds: Quinoa, Almonds
For seeds, Savard recommends quinoa, which you can use in place of rice for a change of pace. It has a similar texture and a nuttier taste. "Cook it just like you cook rice," Savard said. In the end, 3½ ounces has 7 grams of fiber.
As for nuts, almonds are a great source of fiber -- 2.4 grams in a quarter cup packs 56 calories and healthy fats and proteins to boot.
